Why is Gold Put in Fire?

Gold has been a symbol of wealth and luxury throughout history, and one of the most effective ways to refine and purify it is by putting it in fire. In this article, we will explore the reasons why gold is put in fire, and the process involved in refining it through fire.

The Refining Process

Gold is an impure metal, usually containing other elements such as silver, copper, and other minerals. To separate the gold from these impurities, it is put in a fire and subjected to a refining process called smelting. In smelting, the gold is melted at extremely high temperatures, typically between 900°F to 1000°F (427°C to 538°C), and the impurities are separated and removed from the gold.

Purifying the Gold

The gold is then heated to a temperature above 1200°F (649°C) to purify it. This is done to remove any remaining impurities and to remove any tarnish or discoloration that may have formed on the gold during the refining process.

Removing Impurities

Impurities are removed from the gold in several ways during the refining process. Boric acid, for example, is added to the molten gold to remove silver and other impurities. Silica, which is commonly found in rocks and sand, is used to remove arsenic and other toxic substances from the gold.

Types of Fire

There are different types of fire used for refining gold, including:

• Charcoal kilns: These are typically used for smaller batches of gold and provide a hotter and more intense heat.
• Electric arc furnaces: These use electricity to generate heat and are commonly used for larger batches of gold.
• Retorts: These are large containers made of clay or stone that are used to distill gold from the dross.

Gold and the Bible

Gold has played an important role in the Bible, and it is mentioned numerous times as a symbol of wealth and prosperity. In Hebrew, the word for gold is "zahab," which means "to shimmer" or "to gleam." Genesis, the first book of the Bible, tells the story of how Cain and Abel each made offerings to God, with Cain’s offering of the "firstlings of the flock" rejected because it was not an offering of "blood and fat," which was seen as more acceptable. In this context, gold was not mentioned specifically, but the use of the term "firstlings" implies a value equivalent to that of gold.

The 12 Stones

The story of Moses and the 12 Stones provides another example of gold being used as a symbol of wealth and power. When Moses asked the Israelites to contribute stones for the construction of the Altar, Bezalel was tasked with setting aside 12 precious stones, including Turquoise, Copper and Lapis, which were set in 12 foundations to represent the 12 Tribe of Israel. Although gold is not specifically mentioned in this passage, its value as a precious stone is implied by the fact that these 12 precious stones were considered so valuable that they were set into the foundations of the altar.

Why Gold is Put in Fire

To summarize, gold is put in fire because it provides a means of refining and purifying the metal to remove impurities and impurities, making it easier to shape and mold. The process of putting gold in fire also serves to remove tarnish and discoloration from the metal, resulting in a smoother and more shiny surface.
